Abstract

A method is provided for transforming data from a high-dimensional to low-dimensional design space, and for inspecting the transformed data in such a manner as to permit effective navigation and exploration of the high-dimensional design space. Conveniently, an optimum / conditional value for a prescribed functional representation of the transformed data can be derived by visual inspection of a 2-D image map representation of the transformed data. Significantly, the invention has utility for various aircraft design applications and although this technology has been developed with reference to aircraft aerodynamic design in particular, the design space visualisation and curve-fitting technology developed is general. It should therefore be equally applicable to other disciplines such as cost analysis, structures and computational electromagnetics, in which expensive analysis tools are used to find optima for complicated design problems. It is expected to be particularly useful in multi-disciplinary design and situations where there are multiple optima in the design space.

Description

FIELD OF THE INVENTION

[0001] This invention concerns design by space transformation from high to low dimensions. More particularly but not exclusively, this invention concerns methods and systems for design by transforming data from a high to low dimensional design space. BACKGROUND OF THE INVENTION

[0002] There are considerable cost benefits to be derived from improving designs both by better searches in current design spaces and by satisfying more complex design criteria, for instance by striking the right balance between multiple objectives from the same discipline or from different disciplines.

[0003] In known design processes designers typically spend a prohibitively long time preparing individual analysis cases and, are constrained to sampling small areas of the design space close to previously explored regions. In such a design processes, complex design tasks are broken down into manageable portions so that specialists in individual disciplines can resolve different parts of...
